Sony Xperia Z software update brings fix for sudden death bug?

Sony's flagship Xperia Z handset is now receiving its first software update, as the Japanese manufacturer looks to resolve the 'sudden death' bug currently plaguing the device.

It's unclear if the refresh, which carries the build number 10.1.A.1.434, will bring any functionality changes. According to XDA Developers, the Android version - Jelly Bean 4.1.2 - and kernel (3.4.0), remain the same.

The fix is available OTA and via Sony's PC Companion app. It's unclear if there are any discrepancies in regional availability, so let us know what the situation is where you are via the comment section.

Sony unveiled the Xperia Z to much fanfare at CES 2013 back in January. The water and dust resistant smartphone boasts a number of impressive hardware specifications, including a 13-megapixel primary camera and 5in Full HD display.

The Xperia Z measures a super-svelte 7.9mm in girth, offer NFC connectivity, and features a beefy 1.5GHz quad-core S4 Pro chipset plus 2GB of RAM under the hood.
